lnxlink VS hass-workstation-service

Not Deck specific but LNX link sound like something you are looking for. Haven't tried it myself yet, so can't comment how/if it works.

Using Hass Workstation on my desktop and laptop

I use Hass Workstation Service to do that. I configured it to detect when the mic and/or webcam were being used and automate certain actions from Home Assistant

I'm using hass workstation service. The last release included my PR to make a sensor showing what programs are using your microphone. It's now deprecated, but still the only windows program that says WHAT is using the microphone. So my automation runs when that sensor string includes "Teams.exe" or "zoom.exe"

I run HASS Workstation Service on my computer to upload data about my computer's sensors to Home Assistant. When I turn on my computer microphone, the IKEA switch connected to my desk fan turns off automatically

I'm using Hass Workstation Service to achieve this: https://github.com/sleevezipper/hass-workstation-service

I use the HASS workstation service (https://github.com/sleevezipper/hass-workstation-service) for this - it publishes various state entities to HA and I use that to drive the state of a coloured light. I use mic on, video on as the primary drivers for orange or red light, and then time for other colours.

For Home Assistent there is a great software that transmits your PCs microphone and webcam status to HA - https://github.com/sleevezipper/hass-workstation-service

For the automation I use HA with node-red and HASS Workstation Service to detect when mic and webcam are active. When mic only is active, the green light turns on, when the webcam is active it turns red (thanks to u/plasticarmyman for the idea).

I do something similar but using HASS Workstation Service. I detect when the mic is active (which 99% of the times happens when I'm on a meeting) and then change some lights.

No link to original content anymore.. But you can do a bit similar setup with Hass workstation service. https://github.com/sleevezipper/hass-workstation-service If mic or webcam is in use then light goes red. Doesn't take any other statuses, but works for meetings quite fine.
